Those perfect pumps can create the perfect storm for permanent health problems. If you frequently wear high heels, you are setting yourself up for long-term issues. "Extended wear of high heels and continually bending your toes into an unnatural position can cause a range of ailments, from ingrown toenails to irreversible damage to leg tendons. Additionally, cramming your toes into a narrow toe box can cause nerve damage and bunions," says Dr. Nevins. "High heels have also been linked to overworked or injured leg muscles, osteoarthritis of the knee, plantar fasciitis and low back pain," she adds.
